About this map

The Snake River carves a deep path through the canyon lands of Ada and Owyhee Counties, defining the landscape of the Snake River Birds Of Prey Natural Area in the early 1990s. This survey captures a rugged stretch of the river where historical transportation routes intersect with modern conservation and military use. Traces of pioneer history are preserved in the south, where the Oregon Trail (South Alternate) skirts the canyon rim near Wild Horse Butte. Further north, Swan Falls marks a focal point for activity, including an Old Ferry Site and a nearby Radio Facility. The map reveals the intricate topography of the canyon floor, identifying river features like Thomas Flats and Big Foot Bar, alongside small-scale industrial attempts such as a Prospect. To the east, the terrain levels out into the Idaho National Guard Training Area, highlighting the varied jurisdictional uses of this Idaho high desert.
